Murray's first ATP Tour final was in this tournament six years ago, when he was beaten in straight sets by Roger Federer, and he dished out similar treatment to another first-time finalist on Sunday.
The Scot won the first four games before Young finally held to get on the board.
Murray served out the set though and the 22-year-old American, ranked 55th in the world, could make no impact in the second set.
"I just played really well," said Murray on www.atpworldtour.com. "Towards the end of the first set he started to play a bit better, but once I got up in the second I hardly made any mistakes.
"I felt like I was moving well, so it was difficult for him to hit any clean winners. I served very well throughout and didn't give him any opportunities. It was a great match."
Murray hopes his winning start on the Asian swing of the ATP tour will stand him in good stead heading into the Shanghai Masters in a little over a week.
"In terms of the way I'm playing it's very good to get off to a start like that on this stretch and hopefully I can continue that through Shanghai," Murray said. "It's a very good start."
Young, meanwhile, was content with his first ATP final appearance following a breakthrough week in the Thai capital.
"He played well," said Young. "I couldn't do much and it showed in the score. It was great play from him.
"It was my first final on the ATP tour; I've had a semi and the fourth round of a slam, but there's nothing like your first final. It's great. I beat some high calibre players and I played well.
"It was definitely great to win four matches and I'm into the top 50 which is great for me; it was one of my goals at the start of the year.
"I just hope I can build on that and have more tournaments like this."
